To get a car insurance quote from an insurer in Missouri, you will need to submit personal information. The process generally takes 10–15 minutes. MoneyGeek’s Missouri car insurance calculator gives you an estimate based on several factors, including your age, driving record, the coverage levels you select and the type of vehicle you’re insuring.

Adding a teen driver to your policy, your credit score and the coverage levels you choose are the three factors that have the highest impact on car insurance costs in Missouri based on MoneyGeek’s research. Of course, the factor with the most impact on your car insurance costs can change depending on your combination of characteristics.

While the cheapest insurance company for you in Missouri depends on several factors, MoneyGeek’s auto insurance calculator can give you a close estimate.

How Car Insurance Premiums are Calculated in Missouri

Insurance providers look at several factors to determine car insurance premiums. In Missouri, the most important factors are adding a teen driver to your policy, your credit score and the coverage levels you select.

The most significant factor is adding a teen driver to your policy. It has the highest impact on insurance premiums and can nearly increase how much you pay by 2.9x.

How Much Adding a Teen Driver Matters in Calculating Car Insurance in Missouri

Insurance companies consider younger drivers as high risk because of their inexperience, leading to more accidents than older, more experienced drivers. Research shows that nearly half of serious teen driver crashes are due to speeding, being distracted or being unaware of their immediate environment.

That’s why adding a teen driver to your car insurance policy is the most significant factor in terms of the cost of insurance. In Missouri, it can multiply your insurance rates by approximately 2.9x on average.

Insurance providers also consider the teen driver’s age to calculate insurance premiums in Missouri. For instance, adding a 16-year-old driver to your policy will multiply your rate by about 3.1x, higher than adding an 18-year-old driver, which increases your rate by 2.7x.

How Much Credit Score Matters in Calculating Car Insurance in Missouri

If you have a poor credit score, your car insurance costs in Missouri will be higher. Insurance companies believe that drivers with poor credit are more likely to have trouble meeting their payments.

Your credit score can multiply your car insurance rate by 2.4x. Drivers with excellent credit have the cheapest car insurance rates, while those with poor credit scores have the most expensive.

How Much Coverage Levels Matters in Calculating Car Insurance in Missouri

Insurance companies in Missouri also consider how much coverage you buy when they’re calculating your premiums. Choosing an auto insurance policy that comes with a $300,000 bodily injury liability limit and $500 deductible is 2.1x more expensive than a liability-only policy with state minimum limits.

Policies with high coverage levels may lead to a larger payout from the insurance provider in the case of accidents, which explains its impact on insurance rates.

How Much The Age of the Driver Matters in Calculating Car Insurance in Missouri

In Missouri, driver’s age affects the cost of insurance. Younger drivers typically have to pay more for insurance than older drivers due to their inexperience and higher probability of accidents.

Your premium may be twice as expensive, depending on how old you are.

How Much Car Model Matters in Calculating Car Insurance in Missouri

Insurance premiums for a standard car are much cheaper than for sports cars and luxury cars. The cost of spare parts and repairs for luxury cars and sports cars is significantly higher than for sedans. Certain car models also witness an unusually high percentage of theft and vandalism, impacting insurance rates. In general, insurance for a luxury car is 2x the cost of a standard vehicle.

How to Calculate How Much Car Insurance You Need in Missouri

When choosing a policy to insure your vehicle in Missouri, it is important to give equal weight to cost and protection. The amount of coverage you select directly affects insurance rates.

That said, Missouri law requires drivers to have insurance with bodily injury liability protection, property damage liability and uninsured motorist coverage.

Understand Missouri car insurance requirements

In other words, all drivers in Missouri must have 25/50/25 liability insurance. That means at least $25,000 of bodily injury liability per person, $50,000 of bodily injury liability per accident and $25,000 of property damage liability per accident. You are also required to have at least $25,000 of uninsured motorist coverage per person and $50,000 per accident.

Remember that state minimum insurance does not help you with expenses caused by damage to your car because it doesn’t include comprehensive and collision coverage.

Consider Purchasing Additional Liability Insurance

In the event of a major accident, you may need additional liability insurance that is above the state minimum. A car insurance policy in Missouri with $300,000 in bodily injury liability per accident costs an average of $756 per year, compared to $611 for the minimum liability insurance.

Decide whether or not to buy comprehensive and collision insurance

Although Missouri laws do not require you to have comprehensive and collision insurance, you can choose whether or not to include it in your policy. You may need a full coverage policy if your car is leased or financed as it pays for damages in the event of an accident.

In Missouri, the cost of adding comprehensive and collision insurance with a $1,000 deductible is $459 per year. However, if you own an older car with a low replacement value, the cost of comprehensive and collision insurance may not be worth it.

Consider buying additional protection besides these core coverages

More than 16% of drivers in Missouri are uninsured. State law requires uninsured motorist coverage, with all policies to include at least $25,000 coverage per person and $50,000 per accident. This pays for damages if the other driver is uninsured or underinsured.

You may also choose to include personal injury protection insurance to protect against the cost of medical expenses and lost wages after an accident. You have the option of medical payments coverage too, which can help with costs if you or your passengers sustain injuries in a crash.
